To all whom it may concern: v

Be it known that I, CLARENCE E. FRANK- LIN, a citizen of the United States, residing at F ostoria, in the county of Hancock and State of @hio, have invented a new and useful Railway-Torpedo, of which the following is a specification.

This invention relates to railway torpedoes, one of its objects being to provide a device of this character formed of but three pieces, and comprising an inner sealed waterproof case containing the detonating charge, an outer or supplemental sealed waterproof casing and the attaching metal strap which is held to the torpedo by said outer casing.

A further object is to provide a structure of this character which is cheap to manufacture, the two casings being made of paper properly waterproofed and sealed by crimping.

A further object is to provide a railway torpedo including inner and outer casings whereby the detonating charge is doubly protected from moisture and whereby, should the outer case become torn or mutilated in any manner, the charge will still be kept in condition to be exploded.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

v In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a plan view of the torpedo, the free end portions of the attaching strap being removed.

Fig. 2 is a side elevation thereof.

Fig. 8 is an end elevation, the attaching strap being shown in section.

Fig. 4 is an enlarged section on Fig. 1.

Fig. 5 is a plan view of the outer casing prior to being assembled with the other parts.

Fig. 6 is an end view of the outer casing.

Fig. 7 is a plan view of the inner casing prior to being assembled with the other parts.

Specification of Letters Patent.

1921. i Seria1 No. 464, 62 1.

a Fig. 8 is an end view thereof? T Referring to the figures by characters of reference 1 designates a section of fiat paper tubing, the length thereof being substan tially equal tothe width, this section of tubing forming the inner casing of the torpedo and being designed to hold the detonating charge indicatedby dotted lines at 2. The.

Patented m 5.192 1.

outer casing of the torpedo is also made of r a section of flat paper tubing as shown at 3, the length of this tubing being substantially equal to the width and the said tubing 3 being so proportioned as to receive the portion 1 with the charge therein. Before said portion 1 is placed in the casing 3 the open ends thereof are fastened together by crimping in any suitable waterproof manner and the inner casing 1 is then inserted into the outer casing 3 with the crimped ends of the casing 1 against the sides of the casing 3. A metal attaching strap 4 is then inserted through the casing 3 between said casing and the bottom of the casing 1 after which the open ends of the casing 3 are fastened together in a waterproof manner by crimping or the like and as shown in detail in Fig. 4. As both of the casings are waterproof and sealed it will be obvious that the two casings afford double protection to the charge 2 from moisture and even though the outer casing should become torn or mutilated the charge 2 would still be protected by the innercasing.

By means of the band 4; the torpedo can be secured in the usual manner onto a rail.

It will be obvious that the torpedo can v form the inner and outer casings 1 and 3 after which the parts can be quickly assembled as heretofore explained.

What is claimed is 1. A railway torpedo including a fiat tube constituting an outer casing, a flat tube constituting an inner casing and arranged within and extending transversely of the outer casing, an explosive charge within the inner casing, the ends of the inner and outer casings being sealed, and an attaching strap extending between the inner and outer casings and projecting therebeyond. 1

. 2. A railway torpedo comprising flat paper tubes substantially square, an explosive charge contained within one of these tubes,

said tube being housed within the other tube with its ends against the sides of the outer tube -the ends of both tubes being sealed in a waterproof manner, and an attaching band extending between the tubes and laterally therebeyond.

3. A railway torpedo comprising inner and outer flat paper tubes, the inner tube having its ends positioned parallel with the sides of the outer tube, an explosive charge contained within the tube, each of said tubes having its ends sealed to exclude moisture, and an attaching band extending between the tubes and beyond the ends of the outer tube. 4

In testimony that I claim the foregoing as my own, I have hereto afiixed by signature in the presence of two witnesses.
